Assessing the status of oral health integration in South East Asian Regional Office countries' Universal Health Coverage-A scoping review.

BACKGROUND: Oral diseases affect close to 3.5 billion people worldwide and there has been a call by the World Health Organization (WHO) to integrate oral health into the Universal Health Coverage (UHC) agenda. OBJECTIVES: To collate and synthesise information regarding the status of integration of oral health into the health systems covered by UHC across the 11 countries in the South East Asian Regional Office. METHODS: Drawing on the framework of the six building blocks of health systems as devised by WHO, we compared the public dental care coverage models, with a focus on outpatient dental care in these countries. We gathered this information from publicly available resources, databases and peer-reviewed publications to populate the template guided by the WHO Health System Building Blocks. RESULTS: We found a poor access to oral health care, lopsided distribution of manpower, rickety health information systems, and private sector domination and inadequate or absent financing mechanisms for outpatient procedures. The private sector was dominant in all countries except Thailand and Srilanka. Financing was absent in most countries and deficient in Thailand and Indonesia. Dental workforce was deficient in most countries except India, Srilanka, and Thailand. Health information systems were weak with no dental items under price control. Better UHC indicators did not guarantee a lower oral disease burden. CONCLUSIONS: Our review highlighted the close connection between service quality and human resources, governance, and finance. There is a need to establish standardised dental treatment guidelines that are uniformly adopted across countries, integrate oral health into national health and development programs, push for functional oral health research through collecting robust surveillance, economic, and social impact data and the development of cost-effective strategies tailored to each country's unique needs.

Assessment of usefulness and reliability of YouTube™ videos on denture care.

INTRODUCTION: The world's population is in a demographic transition with a rising ageing population. Tooth loss is frequent among older people resulting in the replacement of natural teeth using complete or partial dentures. YouTube™ is the second most popular website in the world and is being increasingly used to access health care information. The aim of this study is to evaluate the usefulness and reliability of the information in YouTube™ videos regarding denture care. METHODS: The YouTube™ website was used to systematically search for videos using the keyword 'denture care'. Videos meeting the eligibility criteria were assessed separately by two independent researchers. The usefulness of the videos was assessed using the Global Quality Assessment Scale and a customized usefulness scoring scheme. Based on these scores, the usefulness of the videos was categorized as low, medium and high. A modified DISCERN tool (mDISCERN) was used for assessing reliability with scores ranging from 0 to 5. Other video characteristics like source/ownership of the videos, duration, views, likes, dislikes, number of days posted, like ratio, view ratio, interaction index and Video Power Index were also obtained. Statistical analysis was carried out using the Kruskal-Wallis test, Spearman correlation test and multiple linear regression analysis. RESULTS: A total of 120 videos were included. Based on the usefulness score, the usefulness of 65.8% of videos were classified as low, 32.5% were medium and 1.6% had high usefulness. The mDISCERN score for 74.2% of videos was 2 or below 2 indicating that the majority of videos had low reliability. Video characteristics did not differ significantly according to the usefulness of videos. Videos uploaded by dentists or dental hygienists had significantly higher usefulness scores (p < 0.001) in comparison to videos uploaded by other sources. However, reliability scores did not differ based on the sources of the videos. Video reliability was found to have a significant (B = 2.08, p < 0.001) positive association with video usefulness. CONCLUSION: YouTube™ cannot be recommended as the only source of information for denture care as most videos received low usefulness and reliability ratings in our study. Dentists and dental health professionals could take an active part in enhancing denture care-related content on YouTube™ and enable patients to have adequate and reliable knowledge of denture hygiene practices.

Oral and Maxillofacial Injuries Associated With E-Cigarette Explosions: A Systematic Review and Management Guidelines Proposal.

PURPOSE: E-cigarettes have become increasingly popular devices used to consume nicotine in recent years. There is a growing body of evidence regarding the risk of spontaneous explosion of these devices causing burn and projectile injuries. The primary purpose of this review was to summarize all injuries to the oral and maxillofacial region secondary to explosion of e-cigarettes. The secondary purpose was to propose an initial management algorithm for such injuries based on the findings in the literature. This review also aims to test the hypothesis that e-cigarette explosive injuries to the oral region were associated with an increased risk of intubation and surgery and examine whether any other injury pattern was associated with an increased risk of intubation or surgery. METHODS: A cohort study based on identifying cases in the literature was conducted to summarize injuries to the oral and maxillofacial region and examine the associations between injury types and location and management. A literature search of the major biomedical databases was conducted in September 2022 using terms such as e-cigarette, explosion, blast, trauma, and burn, among others, which yielded 922 studies. Nonclinical studies, review articles, and studies without injuries to the facial region were excluded. Study subjects were recorded for demographics, device characteristics, injury mechanism, injury location, management, and complications. Chi-squared analysis was used to determine if the predictor variables of type of injury (burn or projectile) and its associated location (ocular, facial, or intraoral for burns and facial thirds for projectile) were associated with the outcomes of intubation and surgical management. The collected data were then used as a guide to propose an initial management algorithm for these injuries. RESULTS: Twenty eight studies, including 20 case reports and 8 case series met the inclusion criteria. A total of 32 explosions of e-cigarettes to 32 patients caused 105 recorded injuries to the facial region. Projectile injuries made up 73.3% (n = 77) of all facial injuries, while burn injuries made up of 26.7% (n = 28). There were 14 (43.8%) patients who suffered both projectile and burn injuries. Burn injuries mostly involved the face (64.3%, n = 18), oral cavity (25%, n = 7), and eye (10.7%, n = 7). The majority (81.8%, n = 63) of projectile injuries occurred in the lower facial third. There were 20 (62.5%) patients who suffered a bone or tooth fracture. Management of injuries involved surgery in 62.5% (n = 20) of patients, which included open reduction and internal fixation of fractures, dental extraction, bone and skin grafts, and ocular surgery. A complication rate of 44.4% (n = 8) was observed across studies that reported on follow-up. There was no statistically significant association between explosive injury to the oral region and intubation or surgical management. There was also no other statistically significant association between any other injury type and location with intubation or surgical management. CONCLUSIONS: E-cigarettes are at risk for spontaneous combustion that can cause serious oral and maxillofacial injuries, particularly to the lower facial third and commonly requiring surgical management. Safety of these devices should be improved through increased user education and regulation.

Legal age determined by a new threshold value of third molar maturity index in subjects with impacted mandibular third molars: An orthopantomographic study in south Indian adolescents.

Third molars are one of the few biological markers available for age estimation in juveniles, especially for the estimation of the 18-year-age threshold. Literature has indicated that impaction has an influence on the development of third molars, which could possibly result in age misclassifications. The present study is intended to identify an alternative cut-off value of the third molar maturity index (I3M) in impacted mandibular third molars and also to evaluate its applicability in estimating the major (≥ 18 years)/minor (< 18 years) status. A total of 1330 digital orthopantomograms (OPGs) of 665 male and 665 female south Indian adolescents aged from 15 to 22 years were collected and assessed. Eight hundred forty OPGs (63.1%) represented test sample, and 490 OPGs (36.9%) represented validation sample. I3M was measured for the total sample. Logistic regression, receiver operating characteristic (ROC) curve analysis, and Youden's index were used to test the performance of the method in the test sample. An alternative cut-off value of I3M < 0.17 was established for the highest value of the Youden's index of 0.598 for both sexes. When tested in validation sample, it has resulted in sensitivity and specificity values of 0.91 (95% CI; 0.86-0.95) and 0.90 (95% CI; 0.78-0.91) in males and 0.86 (95% CI; 0.80-0.92) and 0.90 (95% CI; 0.83-0.95) in females. In conclusion, cut-off value of I3M < 0.17 could accurately discriminate adults from minors with impacted mandibular third molars. However, more work is needed to be done among a more diverse sample to confirm these findings.

Trueness assessment of additively manufactured maxillary complete denture bases produced at different orientations.

STATEMENT OF PROBLEM: The trueness of the intaglio surface of an additively manufactured maxillary denture base may be influenced by the build orientation and the inclusion of support struts. PURPOSE: The purpose of this in vitro study was to compare the trueness of a photopolymer additively manufactured maxillary complete denture base created at different orientations with different support strut designs. Optimizing the build is critical for adopting best practice when fabricating maxillary complete dentures through additive manufacturing techniques. MATERIAL AND METHODS: Denture bases (N=70) were additively manufactured at 5 different build orientations (0-, 15-, 45-, 60-, and 90-degrees) with 10 specimens per orientation. Another 2 groups of 10 were manufactured by using the optimal printing orientation with and without support struts. The denture bases were scanned after storage in artificial saliva at 37 °C, and the scan data were analyzed with a 3D metrology software program. Statistical differences were determined with 1-way analysis of variance (ANOVA) and the Kruskal-Wallis test (α=.05). Color deviation heat maps were used to determine areas of clinically significant dimensional errors. RESULTS: Significant differences were found among groups for positive mean deviation (F=44.09, P<.001), negative mean deviation (F=11.69, P<.001), and root mean square deviation (F=17.11, P<.001) for the different orientations. One-way ANOVA revealed significant differences with the use of support struts in relation to negative mean deviation (F=3.857, P<.001) and RMSE (F=11.215, P<.001) and positive mean deviation (Kruskal-Wallis H=0.070, P=.007). The color deviation maps showed that a 45- to 90-degree print orientation was truest overall and that the addition of support struts to the cameo and intaglio surfaces improved the trueness of the maxillary denture bases. CONCLUSIONS: The build orientation and inclusion of support struts influenced the accuracy of the intaglio surface of additively manufactured maxillary denture bases. A 45- to 90-degree build orientation with support struts on the cameo and intaglio surfaces resulted in the truest denture base.

Child- and family-level factors associated with toothbrushing frequency in a sample of Australian children.

BACKGROUND: Identifying the factors that are conducive to good toothbrushing practices is fundamental for planning oral health promotion interventions. AIM: This study evaluated the relationships between child and family socio-demographic characteristics; children's behaviour during toothbrushing; family support for toothbrushing; parents' practices, attitudes and knowledge related to toothbrushing; general parenting practices; and children's behavioural problems, and children's toothbrushing frequency. DESIGN: A cross-sectional survey was conducted between February and May 2020 with parents of children aged 2-8 years, recruited through childcare centres throughout Australia. Parents completed self-administered surveys on child and family characteristics. RESULTS: A total of 606 parents completed the survey. Only half (52.5%) of the children of surveyed parents brushed their teeth twice or more/day. Children of university-educated parents [odds ratio (OR): 6.48; 95% confidence intervals (CIs): 1.21-34.71] and those concerned about their child's toothbrushing (OR: 1.44; 95% CI: 1.21-1.72) were more likely to brush twice or more/day. Where children were non-compliant during toothbrushing or parents reported using ineffective parenting strategies during toothbrushing, children were less likely to brush their teeth twice or more/day. Lack of concern of parent about toothbrushing was associated with brushing less than twice/day in children CONCLUSIONS: Measures of parenting and child behaviour that were specific to the toothbrushing context were associated with twice daily brushing while general measures of parenting and child behaviour were not correlated with twice daily brushing.

Clinical efficacy of a new cetylpyridinium chloride-hyaluronic acid-based mouthrinse compared to chlorhexidine and placebo mouthrinses-A 21-day randomized clinical trial.

OBJECTIVE: To compare the effectiveness of a novel cetylpyridinium chloride (CPC)-hyaluronic acid (HA)-based mouthrinse with chlorhexidine (CHX) and placebo mouthrinses in preventing plaque and gingivitis. The secondary outcomes were calculus, extrinsic stains, oral malodour and occurrence of adverse events. METHODS: A 21-day randomized, double-blind, three-arm parallel study with random allocation of young dental students to any of the three mouthrinse groups. Thorough prophylaxis was done at baseline followed by a baseline examination for oral malodour, extrinsic stains, calculus, gingivitis and plaque by a single examiner. All the subjects used the allocated mouthrinse twice daily for 21 days and were examined again at the end of the experimental period. They were also interviewed for adverse events. Change in the scores of clinical indices was calculated and compared between the groups. RESULTS: A total of 75 subjects were included and completed the experiment. There was a significant difference for change in plaque index scores between the groups (P = .015); subjects in the placebo group experienced higher levels of plaque accumulation than the other groups. Teeth staining increased in the CHX (P < .001) and placebo groups (P = .002), but not in CPC-HA users (P = .573). No significant differences were found between the three experimental groups for change in the gingival index (P = .08), calculus scores (P = .494), oral malodour (P = .870) and reporting of adverse events (P = .249). CONCLUSIONS: CPC-HA and CHX had similar effectiveness in preventing plaque accumulation, while no differences were observed between the mouthrinses for preventing gingivitis. Dental staining was caused by CHX and the placebo mouthrinses but not by CPC-HA mouthrinse.

Reliability and validity of Arabic Rapid Estimate of Adult Literacy in Dentistry (AREALD-30) in Saudi Arabia.

BACKGROUND: To evaluate the reliability and validity of Arabic Rapid Estimate of Adult Literacy in Dentistry (AREALD-30) in Saudi Arabia. METHODS: A convenience sample of 200 subjects was approached, of which 177 agreed to participate giving a response rate of 88.5%. Rapid Estimate of Adult Literacy in Dentistry (REALD-99), was translated into Arabic to prepare the longer and shorter versions of Arabic Rapid Estimate of Adult Literacy in Dentistry (AREALD-99 and AREALD-30). Each participant was provided with AREALD-99 which also includes words from AREALD-30. A questionnaire containing socio-behavioral information and Arabic Oral Health Impact Profile (A-OHIP-14) was also administered. Reliability of the AREALD-30 was assessed by re-administering it to 20 subjects after two weeks. Convergent and predictive validity of AREALD-30 was evaluated by its correlations with AREALD-99 and self-perceived oral health status, dental visiting habits and A-OHIP-14 respectively. Discriminant validity was assessed in relation to the educational level while construct validity was evaluated by confirmatory factor analysis (CFA). RESULTS: Reliability of AREALD-30 was excellent with intraclass correlation coefficient of 0.99. It exhibited good convergent and discriminant validity but poor predictive validity. CFA showed presence of two factors and infit mean-square statistics for AREALD-30 were all within the desired range of 0.50 - 2.0 in Rasch analysis. CONCLUSIONS: AREALD-30 showed excellent reliability, good convergent and concurrent validity, but failed to predict the differences between the subjects categorized based on their oral health outcomes.

Do dental anxiety and satisfaction with dental professionals modify the association between affordability and dental service use? A population-based longitudinal study of Australian adults.

OBJECTIVES: This study aimed to assess the association between affordability in terms of difficulty paying dental bills in Australian dollars and dental service use in the presence of sociodemographic confounders, and to assess the role of dental anxiety and satisfaction with dental professionals as mediators. The second aim was to investigate how dental anxiety and satisfaction with dental professionals modify the association between affordability and use of dental services in Australian adults. METHODS: Longitudinal data from the Australian National Study of Adult Oral Health (2004-06 and 2017-18) was used. Poisson regression and path analysis were conducted to determine the association between affordability and frequency of use of dental services. Effect measure modification (EMM) analysis was performed by stratification of dental anxiety and satisfaction with dental professionals. RESULTS: The study included 1698 Australian adults and identified that the prevalence of low frequency of dental visits was 20% more for those who had difficulty paying dental bills. Adults with dental anxiety (prevalence ratio [PR] = 1.14) and those who were dissatisfied with dental professionals (PR = 1.17) had a higher prevalence of low frequency of dental visits in the presence of difficulty paying dental bills. This indicated that dental anxiety and dissatisfaction with dental professionals were effect modifiers on this pathway. CONCLUSIONS: Adults who experience dental anxiety and dissatisfaction with dental professionals are more likely to avoid dental visits when faced with difficulty paying dental bills. However, it is important to note that these associations do not necessarily imply a causal relationship.

Theories, Models, Frameworks, Guidelines, and Recommendations for Trauma-Informed Oral Healthcare Services: A Scoping Review.

BACKGROUND: Traumatic life experiences (TLE) are common and can affect a person's physical being and health-related behaviors, including those related to oral health. This scoping review aimed to identify evidence exploring the implementation and provision of trauma-informed care (TIC) in oral health services delivery. METHODS: Arksey and O'Malley's framework with enhancements proposed by Levac et al. and Peters et al. was used. Studies were selected based on a preset inclusion and exclusion criteria and the population/concept/context framework. Primary charting of descriptive data was conducted, followed by thematic analysis to identify ideas common within the included literature. Searches were conducted in Medline (via Ovid), APA PsycINFO (via Ovid), Embase (Elsevier), Scopus, CINAHL (via EBSCO), and Cochrane databases. Google Scholar and ProQuest were used to identify grey literature. RESULTS: The search identified 251 records, with fifteen records meeting the inclusion criteria. Limited models, frameworks, and recommendations for trauma-informed practices in oral health services were identified. Recommendations for TIC practices were identified, and clinical practice adjustments for dental practitioners were described to improve service delivery for patients who may have experienced trauma. Avenues for future research were identified. CONCLUSIONS: Limited evidence exists to guide trauma-informed practice in oral health service delivery. This scoping review highlights the need for further research into approaches and practices of TIC for oral health services delivery to assess their efficacy and the need to develop evidence-based TIC frameworks to meet the unique needs of oral health service providers and populations.
